MECHANlOALLY-PLAYING ACCORDION- Specification of Letters Patent.

katented April 17', 1906.

Application filed August 15, 1904. Serial No. 220,717.

To aZZ whom it may concern.-

Be it known that I, ALFRED ZULEGER, a subject of the King of Saxony, residing at 6 Konigsplatz, Leipsic, in the Kingdom of Saxony and Empire of Germany, have invented new and useful Improvements in Mechanically-Playing Accordions, of which the following is a specification.

My invention relates to mechanically-playing accordions.

The mechanically-playing accordions heretofore known have the drawback that the tongues or reeds provided in the same are too restricted in number and that therefore the music produced with them leaves very much to be desired as regards fullness of tone and sonorousness. This is due to the fact that the arrangement of the tongues or reeds and of the cells did not enable a suflicient number of the same to be located in the case of the accordion.

According to my said invention this drawback is obviated by dividing each of the cells, which are arranged in the known manner in several rows, the cells of one row alternating with those of the other row, into two con1- partments by a partition provided with an aperture, each cell being controlled by a single flap or valve, so that double the number of tones may be played with the instrument without increasing the space occupied by the cells and valves and the mechanism for oberating the latter.

In the accompanying drawings I have represented an accordion with the improved arrangement, Figure 1 being a partial section of the same, and Fig. 2 being a side View showing the flaps or valves controlling the tongues or reeds.

The case a of the accordion is divided by a partition I), provided therein, into two compartments c and d, the latter com artment containing the flaps or valves whic control the tongues or reeds and the former compartment serving for the reception of the driving mechanism e, which may be of any suitable construction, and of the tune band or sheet f, adapted to be operated by toothed wheels at the proper rate.

Upon the board 9, inside the compartment (Z, the flaps or valves h h if 7L3 are arranged side by side in several rows placed. one behind the other, the flaps or valves of one row alternating with those of the other rows. Below the board 9 I provide in the middle of each row of flaps or valves the cells 'i, having their middle partition 7:: formed with an aperture Z, which connects the two compartments of each cell with one another, while the tongues or reeds m are arranged, as usual, at the sides of the cells i, the said tongues or reeds being caused to sound by the wind produced in the instrument on the opening of the flaps or valves when the bellows is extended or contracted. The flaps or valves h h 7L2 7L controlling the tongues or reeds m, are con nected by rods n n n n with the operatinglevers p, pivoted at 0. By their free end forming a nose the said levers protrude through slots furnished in a metallic plate 7", extending over the whole width of the ac cordion, and they are normally depressed by the tune band or sheet f, forced by a presserbar 8 against the plate 1, thereby keeping the flaps or valves h closed, while when an operating-lever p enters a slot in the tune band or sheet the corresponding flap or valve is opened by positive motion, and the tongues or reeds of the cell uncovered by the same are caused to sound.

The tune band or sheet f receives its movement by driving mechanism 6, which is kept in operation through the agency of a lever 75, adapted t0 be moved by hand from the outside. 85

l/Vhat I claim as my invention, and desire to secure by Letters Patent, is

1. In an accordion of the class described, cells arranged in several rows, the cells of one row alternating with those of the other rows, partitions dividing each cell into two compartments and provided with an aperture, reeds arranged at each side of the cells, reedcontrolling valves, a single valve being provided for each cell, operating-levers coning a free communication between the two nected each with one of the said Valves, a parts of each cell, a Valve for each cell and tuning-band provided with slots for the pasmeans for controlling the valve. sage of the said operating-levers, a presser- In testimony whereof I have signed my 5 bar adapted to force the tuning-band against name to this specification in the presence of :5

the plate, and means for operating such tuntwo subscribing witnesses.
